i can't see why she would want to take his phone in some episode yukiko comes as if she is conan's mom and she gave mouri 1000000 yen so Ran probably have guessed that they're rich and why does she even care about conan's cell phone? i only hve one question about cellphones in DC conan is actually 17 so its normall for him to have a cellphone but why does the DB have cellphones? ( how come those 6-7 years old children have cellphones )
